iPhone 4S vs Samsung Galaxy S II

OS

Galaxy S II: The excellent Android 2.3.3 with TouchWiz 4.0 makes access to everything simple and personalized. The pull-down options are convenient with smooth transitions.
iPhone 4S: If you've got a house full of Apple products, you'll like the new Mirroring feature in iOS 5 which lets you play your iPhone 4S's 720p video on your Apple TV, via AirPlay tech that's usually reserved for music streaming. There are also pull-down Notifications, Reminders and iMessage integrated into your SMS and Twitter is – unsurpisingly – all over the new OS. The iPhone 4S's secret weapon is its voice recognition feature, Siri – see how much we loved it in our hands-on and first impressions video – but there's nothing to stop Android app developers stepping up their voice control game.

VERDICT So, we've tiptoed along the fence so far but finally fallen off into Apple's side with the temptation of the superior App Store beckoning – the same reason the iPhone 4 has ruled our top ten since its launch last year. The iPhone 4S hasn't stunned us spec-wise but it has done enough to edge itself ahead of the best of Android – in other words the Galaxy S II.
